Gerald,

I would stress that the size terminology is based on EPSG
terms, and EPSG is the basis of GeoTIFF (for better or worse).

I shall mark your and Janne's email for future reiew, but
even if I am able to correct a few things I won't be attempting
to address the terminology question.

I would love for such a thing to exist in a form that can be easily related
to various software systems and file formats. I would love to see such
an effort attacked as a "MetaCRS" effort - that is collaboratively amoung
the various experts here, the CS-Map community and some of the other
OSGeo coordinate system efforts (ie. GeoTools).

Best regards,
